The accompanying data set gives the additional sleep in hours obtained by a sample of 10 patients using a certain sleep aid. Preliminary data analyses indicate that the t-interval procedure can reasonably be applied. Complete parts (a) and (b) below. Click here to view the additional sleep hours. Click here to view page 1 of the t-table. Click here to view page 2 of the t-table. a. Obtain and interpret a 99% confidence interval for the additional sleep that would be obtained on average for all people using the sleep aid. (Note: x=2.08 hr and s=1.979 hr.) The 99% confidence interval is from hour(s) to hour(s). (Round to two decimal places as needed.) Interpret the 99% confidence interval. Select all that apply. A. 99% of all possible random samples of 10 people using the sleep aid would have mean additional sleep times that are between the interval's bounds. B. 99% of all people using the sleep aid would obtain additional sleep times that are between the interval's bounds. C. With 99% confidence, the mean additional sleep that would be obtained by all people using the sleep aid is between the interval's bounds D. There is a 99 % chance that the mean additional sleep that would be obtained by all people using the sleep aid is between the interval's bounds. b. Was the sleep aid effective in increasing sleep? Explain your answer. that the sleep aid was effective in increasing sleep, since the 99% confidence interval's is

Additional Sleep Hours 1.8 0.7 0.8 -0.4 C Print -0.2 4.0 5.2 1.5 Done 4.5 2.9 0

b. Was the sleep aid effective in increasing sleep? Explain your answer. that the sleep aid was effective in increasing sleep, since the 99% confidence interval's With strong confidence, it appears It cannot be concluded with strong confidence.

b. Was the sleep aid effective in increasing sleep? Explain your answer. that the sleep aid was effective in increasing sleep, since the 99% confidence interval's center is upper bound- lower bound

b. Was the sleep aid effective in increasing sleep? Explain your answer. greater than less than that the sleep aid was effective in increasing sleep, since the 99% confidence interval's
